Define shell variable HISTIGNORE so that comments (lines starting with #) appear in shell history
I was surprised to find that with RedHat bash, I could not find any comment lines (begining with #) in my bash shell history. Surprised because in Mageia Linux this works. It turns out that RedHat's bash will keep comment lines if in my .bashrc, I define: export HISTIGNORE=' cd "`*: PROMPT_COMMAND=?*?' Why have comment lines in shell history? It's a handy and convenient way to make proto-commands (to be completed later) and for storing brief text data that is searchable in shell history.

List files with full path
This version is a bit more portable although it isn't extended as easily with '-type f' etc. On AIX the find command doesn't have -maxdepth or equivalent.

Selecting a random file/folder of a folder
Also looks in subfolders

Use the aliased command 'nsl'
